(a) A person drinks four glasses of cold water (3.0°C) every day. The volume of each glass is 2.5x10^2 mL. How much heat (in kJ) does the body have to supply to raise the temperature of the water to 37°C, the body temperature? (b) How much heat would your body lose if you were to ingest 8.0x10^2 g of snow at 0°C tp quench thirst?

    a)
    q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
    q will be in J, convet to kJ.

    b)
    q = (mass snow x heat fusion) + [mass melted snow x specific heat H2O x (Tfinal-Tinitial)]
    Tfinal = 37
    Tinitial = 0
